PROPELLING DEVICE FOR BOATS.

SPECIFICATION forming part of Letters Patent No. 314,734, dated h farch 31, 1885..

Application filed July 25,1884. (No model.)

T aZZ whom, it may concern:

Be it known that 1, CHARLES F. SMITH, of the city, county, and State of New York, have invented a new and Improved Propelling Device for Boats, of which the following isa full, clear, and exact description.

The object of my invention is to provide a new and improved device for propelling boats, which device can easily be reversed to prope in either direction.

The invention consists in the construction and arrangement of parts, as will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of a boat provided with my improved propelling device. Fig. 2 is an enlarged longitudinal sectional elevation of the propelling device. Fig. 3 is a side view of the same. Fig. 4 is a cross-sectional view on linear; 00, Fig. 2. Fig. 5 isa detailiongitudinal view of the end of the device. Fig. 6 is a cross-sectional elevation on the lineyy, Fig. 5.

Atube, A, ofwood orinetal, or arod, is provided at one end with a handle, B, and at the opposite end with a pointed tapered or like head, 0. At the pointed end the tube A is provided with two fixed collars, F, a short distance from each other, and between the collars it is provided with two diametrically-opposite longitudinal slots, D.

On the slotted part of the tube A, between the collars F, a sleeve, E, is mounted to slide, the length of which is less than the distance between the collars F. The sleeve Eis provid ed with a cross-piece, G, which passes through the slots D, and is secured to the inner end of a rod, H, held within the tube A, and provided on its outer end with a handle, J. The rod H is also provided with apertures 71, through which a pin, H, can be passed for the purpose of locking the rodinplacein the tube A. The sleeve E is provided diametrically opposite with jaws J, to which blades or wings K are hinged, which may have any suitable shape, but are preferably made almost square, and are provided in the inner edges with recesses, as shown.

From each side of each wing or blade R a quadrant lug, L, or likelug or projection, projects downward and outward. If desired, the sleeve E can also be provided with longitndinal slots to coincide with the slots D.

The above-described propelling devices are held in rowlocks or other guides on the bow or stern of the vessel,and are operated by hand, foot-power, or machinery. If they are to be operated by machinery,they are made heavier and larger, and other devices are provided for lockingthe rods in their different positions or shifting them.

The operation is as follows: The boat can be propelled forward from the bow by pulling on the tubes A, or from the stern by pushing on the tubes, or the boat can be propelled backward from the bow by pushing on the tubes or from the stern by pulling on the tubes. As shown in Fig. 2, the device is adjusted for propelling the boat forward in the direction of the arrow a from the bow by pulling the tubes A in the inverse direction of the arrow a and pushing them in the direction of the arrow a. When the tube A is pulled in the inverse di rection of the arrow to, the wingsK-are swung in the direction of the. arrows 8/ until their outer stops or lugs L rest on the outer collar, F, or on the tube A, and the wings are at right angles to the tube A. When the tube A is moved in the direction of the arrow 0/, the pressure of the water folds the wings in the inverse direction of the arrows b, the inner prongs L passing through the slots D into the tube A, and so on alternately. The

'wings K have a large surface on which the water can act, the outer lugs L preventingthe wings from swinging outward farther than into a position at right angles to the' tube A. If the boat is to be propelledin theinverse direction, the pins H are removed and the rod H of each tube A pulled in the inverse direction of the arrow a, whereby the sleeves E are shifted, and the inner ends of the slots D are closed and the outer ends opened. Then the rod H is locked in position. If the tube Ais pushed in the direction of the arrow 0, the wings K can swing into a position at right angles to the tube A, but not farther, but can swing against the tube when the same is pulled in the inverse direction of the arrow a, as the outer lugs L can thenpass into the outer ends of the slots D.

The propelling devices can also be used for steering the vessel from the bow or stern by holding one device fixed and operating the other, or by operating two devices in opposite directions.

I have shown two wings, but three, four, or more wings or blades may be attached, as occasion may require, and in such cases the shapes of the blades must be varied, so as to permit of their'being pivoted to the sleeve.

One or more men may operate in each propelling device, and the said propelling device may be arranged at different inclinations, as

occasion may require.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. Thecoinbination, with a tube, of a sliding sleeve on one end of thes'ame,wings hinged on the sleeve, stop-lugs projecting 'from'both sides of the wings, and devices for adjusting or shifting the sleeve, substantially as herein shownand described.

'ingsleeve on one end of the same,wings hinged '2. The'combination, with a tube, of a slidon t-hesleeve, stop-lugs on the wings, a rod held to slide within the tube, and having its inner end'connected with'the sleeve, and devices for locking the rod and sleeve in'pla-ce, substantially as herein shown and described.

3. The combination, with the tube A, having longitudinal slots D at one end, of the sliding sleeve E over the slots, the wings K',hinged Y to the sleeve, the stop-lugs L on the wings, the rod H within the tube A, which rod is connected with the sleeve, and of devices for locking the rod H in place, substantially as herein shown and described.

4. The combination, with the tube A, having two fixed collars, F, and longitudinal slots D between them, of the sleeve E, mounted to slide on the tube between the two collars, the

'Win'gs'K, hinged to the sleeve, the stop-lugs L CHARLES SMITH;
